Arcpy - Avoid creating tables and use the generated features directly

Question

We have a database containing line segments.

Due to certain particularities in our project, we need to perform some analysis operations line by line instead of just performing the operation in the whole feature class (please don't question this seemingly bad decision, this is not the scope of this question and we have our reasons for doing that).

Now, this cerainly leads to a performance penalty (of course).

When performing the analysis (such as using arcpy.Buffer_analysis), a new feature class is created, and we need to access the results via cursor.

fields= ["OID@", "SHAPE@", ....]
with arcpy.da.SearchCursor(table, fields) as cursor:
    for line in cursor:
        shape = line[1]    

        #here, a feature class is being created, but I just wanted the buffer feature itself
        buffer = arcpy.Buffer_analysis(shape, r'in_memory\Buffer', DistBUFFER, "FULL", "FLAT")

        #here we need to use a cursor to access the created buffer
        with arcpy.da.SearchCursor(buffer, otherFields) as anotherCursor:
            ... do stuff ...

Is there a way to use the analysis functions without creating a new feature class? I mean, make the analysis return the objects directly in a list in the buffer variable, bypassing the create feature and use cursor steps??
